A Mezuzah Scroll is a piece of parchment carved with specified Hebrew verses from the Torah. These verses consist of the Jewish prayer "Shema Yisrael", starting out with the phrase: "Hear, O Israel, the LORD our God, the LORD is One"

These are written on the parchment with the use of an exceptional ink, by an extremely skilled and certifiable scribe. The text is written in one column on twenty two scored lines. All letters should be written in good order, for if in case a letter is written wrong then the Mezuzah would not be good to use.On the parchments back the word 'Sha-dai' is written, together with some other letters. Once the scribe has finished his writing, the parchment is then rolled from left to right, in order for the first word 'Shema' to show up once you open the Mezuzah.

A Mezuzah is an everyday reminder ― and a public proclamation ― of Jewish faith and identity.Although Mezuzah literally stands for "door-post," it generally cites a scroll of parchment consisting of biblical verses, attached to the door-post of all Judaic households to carry out the Mitzvah in inscribing the words of the Shema "on the doorposts of your house". Others construe Jewish law to involve a Mezuzah on all doorways in the home not including the bathrooms, and closets that are too small to be considered as rooms. The parchment is made by an eligible scribe (a "sofer stam") who has gone through a lot of years of precise training, and the verses are written using a black indelible ink with a special quill. The parchment is then rolled up and placed inside a Mezuzah case.

The Talmud alleges that an appropriate Mezuzah provides security of the home. A king at one time gave a Rabbi a diamond as a gift, so the Rabbi gave the king a Mezuzah as a gift. The king did not know what it was, and felt insulted. The Rabbi explained to the king, "I will be needing guards to protect my home due to the present you gave me, but the gift I presented to you will give protection to your home!"

Keeping the teachings of the Torah always bestows blessings, and the Talmud says that holding on to the teachings of the Mezuzah imparts long life and is used to protect one’s home. Naturally, the more blessed our home is retained, the more the protection. Hence we must always take caution of what we bring inside our homes. When we are ready to bring something into our home, whether it is food for thought (magazines, books, etc.), or food to eat, we need to consider and stop, whether or not it will embarrass the Mezuzah to have that carried past in the home. If we do this, and guard our homes from spiritual attack, we can be certain that our homes will continuously be protected from physical assault.

A Mezuzah is not a talisman. The Rambam shows that to treat it as one degrades the Mitzvah. However, one of the special benefits of the Mitzvah is that it guards he who performs the Mitzvah from damage that may otherwise occur him.
